Multiple vulnerabilities has been found and corrected in mono: IOActive Inc. found a buffer overflow in Mono.Math.BigInteger class in Mono 1.2.5.1 and previous versions, which allows arbitrary code execution by context-dependent attackers (CVE-2007-5197). Multiple cross-site scripting (XSS) vulnerabilities in the ASP.net class libraries in Mono 2.0 and earlier allow remote attackers to inject arbitrary web script or HTML via crafted attributes related to (1) HtmlControl.cs (PreProcessRelativeReference), (2) HtmlForm.cs (RenderAttributes), (3) HtmlInputButton (RenderAttributes), (4) HtmlInputRadioButton (RenderAttributes), and (5) HtmlSelect (RenderChildren) (CVE-2008-3422). CRLF injection vulnerability in Sys.Web in Mono 2.0 and earlier allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via CRLF sequences in the query string (CVE-2008-3906). The XML HMAC signature system did not correctly check certain lengths. If an attacker sent a truncated HMAC, it could bypass authentication, leading to potential privilege escalation (CVE-2009-0217). Packages for 2008.0 are being provided due to extended support for Corporate products. The updated packages have been patched to fix these issues. Affected: 2008.0
